Abstract: Abstract of the Disclosure:  Method and apparatus for heating a subterranean formation in which a plurality of wells are completed in a predetermined pattern, characterized by heating the subterranean formation by electrical conduction under conditions such that the electrical current flowing at different subterranean points in the subterranean formation, or adjacent thereto, varies at different times because of differ-ent current flow patterns to attain a more nearly uniform heat-ing of the subterranean formation.  Each of the wells in the pattern has a predetermined arrangement of electrical conductors therein, each of which is connected to a different terminal of a multi-phase current source so as to change sequentially in time the direction of the subterranean current flow between the different conductors.  Also disclosed are a plurality of methods and apparatus, including the preferred embodiments of this invention.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of and apparatus for toning an exposed electrophotographic member in a camera or other electrostatic imaging device which uses liquid toner comprising toner particles suspended in dispersant.             The method contemplates running the liquid toner into a chamber containing the photoconductive surface of the electrophotographic member and a metal plate parallel with one another and spaced apart as two boundaries of the chamber.  During the toning operation, a low d.c. bias potential is applied across the chamber between the photoconductive surfaces and the plate of a polarity such as to repel toner particles from the photoconductive surface and drive them from the surface toward the plate, but the voltage of the bias is low enough not to affect increments which have substantial charge on them.  The result is that incre-ments with very little charge are left with practically no adhering particles.  When the toning is completed, the bias is substantially increased to cause attraction by the plate so that particles floating in the liquid toner which have not been adhered to the surface tend to move toward the plate. Since the majority of particles have already adhered to the latent image of the photo-conductive surface, the toner is cleared of floating particles and can be run out of the chamber leaving the toned image clean of particles in the untoned areas.                 The invention contemplates apparatus which enables the method described to be carried out.

Abstract: SUSTAINED RELEASE DRUG DELIVERY DEVICE               AND PROCESS FOR MAKING SAME     ABSTRACT OF THE DISCLOSURE      Sustained release diffusional drug delivery devices for use in an aqueous body environment are disclosed.          The devices are in the form of an integral solid body that is sized and shaped for placement and retention in the environment and are made from a mixture of drug, polymer, and a small amount of discrete depots of an osmotically effective solute.  The polymer is permeable to water and drug, insoluble in the environment, and impermeable to the solute.  The solute depots are dispersed in the polymer such that they are encapsulated sub-stantially individually by a layer of polymer.  When the device is placed in the environment, the depots imbibe water and burst the polymer layers surrounding them, thereby forming a network of interconnected pores through the device and thus increasing in situ the surface area from which drug may be released from the polymer to the environment.  This in situ increase in surface area increases the rate of drug release from the device.

Abstract: ABSTRACT OF THE DISCLOSURE      Head switching control apparatus for use in video signal processing apparatus of the type comprised of plural rotary trans-ducer heads which scan successive tracks  across a recording medium, each track having recorded therein a composite video signal com-prised of video information, horizontal synchronizing signals, and a vertical blanking interval.  The head switching control apparatus functions to selectively connect individual transducer heads, one at a time, to video signal receiving circuitry.  This head switch-ing control apparatus is comprised of a position pulse generator for generating position pulses representing the relative positions of the transducer heads with respect to the recording medium. A bi-state circuit has first and second states and is responsive to successive position pulses for switching between its first and second states as the transducer heads rotate into predetermined positions relative to the recording medium.  Switching circuitry is coupled to the transducer heads to electrically connect indi-vidual ones of the heads to the video signal receiving circuitry. A synchronizing  signal separator is coupled to the video signal receiving circuitry and separated the synchronizing signals in-cluded in the vertical blanking interval from the video signal. A switch pulse generator is coupled to the synchronizing signal separator and to the bi-state circuit and is responsive to the first and second states of the bi-state circuit for generating switch pulses which are synchronized with the separated synchroniz-ing pulses.  These switch pulses are applied to the switching cir-cuitry for selectively actuating that circuitry so as to connect the transducer heads, one at a time, to the video signal receiving circuitry.

Abstract: OPEN BOTTOM FLOAT TENSION RISER                  ABSTRACT OF THE DISCLOSURE          A marine riser, which is hung from a drilling platform floating on a body of water and connected at its lower end to a wellhead, is buoyantly tensioned by one or more float cans with open bottoms.  These float cans are connected at their upper end to the riser to which air under pressure is controllably supplied.  The pressurized air blows out the water in each can to achieve the desired buoyancy.  The float can may have an air dump valve interconnected with similar valves in the other cans.  The function of these valves is to release the pressurized air in the can if the riser parts.  At the upper end of the riser is a slip joint, which may include safety water-dampening gear to further reduce upward motion of a parted riser.  The optional dampening gear comprises an annular piston formed by the upper section of the slip joint that forces water through ports in the exterior of the lower section of the slip joint as the riser below the slip joint moves upward.  A method of running this riser includes the steps of lowering the riser with or without:  the air under pressure flowing into the float cans, a ballast weight at the bottom end of the riser, and supplementary tensioning or motion compensating equipment.  The riser's descent may be stopped at a point above a water bottom connector at which time motion compensating equipment may be engaged and then gradually lowered to make the connection.  The foregoing is reversed when removing the riser from the water bottom connection.
